What Our Clients Say

How Is A Blower Door Test Conducted?

In preparation for blower door test in New Milford borough, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

Preparing for a Blower Door Test in New Milford borough, NJ

Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in New Milford borough, NJ.
